1 PROTOCOL 11 FOR CONTAMNATED STES Upper Cap Concentrations for Substances Listed in the Contaminated Sites Regulation ersion 2.2 Prepared pursuant to Section 64 of the Environmental Management Act Approved: Michael W. Macfarlane Feb 5, 2014 Director of Waste Management Date

2 1.0 Definitions The following words, acronyms and expressions used in this Protocol are defined in the ministry procedure Definitions and Acronyms for Contaminated Sites : receptor, Regulation, and upper cap concentration. 2.0 ntroduction Protocol 12, Site Risk Classification, Reclassification and Reporting, describes procedures for classifying sites based on their risk to the environment or human health. Conditions for classifying sites as high risk include the presence of substances at concentrations exceeding upper cap concentrations. These are concentrations established by the Director for substances with numerical standards in the Regulation and which, when present in the exposure zone of soil, water, sediment or vapour, could pose high risks to the environment or human health. Under Protocol 12, if upper cap concentrations are exceeded, an analysis of exposure pathways usually must be carried out to determine if a site is classified as high risk. 3.0 Upper cap concentrations Tables 1 8 specify the upper cap concentrations for soil, water, sediment, and vapour under this protocol. For the purposes of selecting upper cap concentrations the methods incorporated in sections 11 (Definition of contaminated site) and 12 (Specification of applicable land, water, sediment and vapour uses and site-specific factors) of the Regulation and ministry protocols and guidance should be followed. 4.0 Derivation of upper cap concentrations Upper cap concentrations were generally derived from the numerical environmental quality standards and criteria in Schedules 4, 5, 6, 9, 10, and 11 of the Regulation by applying multiplication factors or upper cap multipliers. They were established in consideration of toxicological data sets for multiple species or humans and of the level of unacceptable risk that exposure to an upper cap concentration of a substance would provoke in media-specific receptor populations. Details on the derivation are provided in Appendix 1. For more information, contact the Environmental Emergencies and Land Remediation Branch at site@gov.bc.ca

31 1. All values are in ug/g dry weight (dwt) unless otherwise stated. Substance must be analyzed using methods specified in a director s protocol or alternate methods acceptable to the director. 2. Upper cap concentrations were derived by application of a 10x upper cap multiplier to existing Schedule 9 sediment quality criteria for substance and corresponding sediment type. 3. Upper cap concentration is applicable to freshwater aquatic life. 4. Upper cap concentration is applicable to marine and/or estuarine aquatic life. 5. Sensitive sediment means sediment at a site with sensitive aquatic habitat and for which sensitive sediment management objectives apply. Consult director for further advice. 6. Typical sediment means sediment that is not sensitive sediment. Consult director for further advice. 7. Denotes an upper cap concentration which is considered less reliable or that could not be fully evaluated. 8. Total PCBs includes either the sum of four to seven Arochlor mixtures (i.e. Arochlor 1016, 1221, 1232, 1242, 1248, 1254 and/or 1260) or the sum of > 20 individual PCB congeners. No discrete upper cap concentration for Arochlor 1254 was derived, since the existing Canadian Council of Ministers of the Environment interim Probable Effects Level (PEL) for that substance was inconsistent with the PEL provided for total PCBs and the Probable Effects Level (PEL) for Arochlor 1254 was derived using methods different from those used to derive the upper cap concentration for total PCBs listed in this table. 9. Calculated using data for PCDDs, PCDFs, PCBs and associated PCDD, PCDF and PCB toxicity equivalency factors. 10. Upper cap concentration is derived from Schedule 9 sediment criteria, which was set equal to the State of New York, Department of Environment Conservation, 1994 criterion for the substance. 11. Upper cap concentration is derived from Schedule 9 sediment criteria, which was set equal to the Washington State, Department of Ecology, 1991 criterion for the substance. 12. PAHs (total) includes: 2-methylnaphthalene, acenaphthalene, acenaphthene, anthracene, benz[a]anthracene, benzo[a]pyrene, chrysene, dibenz[a,h]anthracene, fluorene, fluoranthene, naphthalene, phenanthrene, and pyrene. 13. DDD is 2,2-bis(p-chlorophenyl)-1,1-dichloroethane. 14. DDE is 2,2-bis(p-chlorophenyl)-1,1-dichloroethylene. 15. DDT is 2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane. 16. Lindane is 1,2,3,4,5,6-hexachlorocyclohexane, gamma isomer
